Puns can be a hit a miss affair, but often work well if they are topical and have multiple layers (subtext) to them.

This pun has the language side going for it, but needs more to it. I keep away from them, because I can't drive them properly. Keep working on the idea - it's a good way to enrich your craft. ut they are difficult to fashion into strong ideas.

Also, picking fights with people who want to pick a fight with you looks tiresome from the outside. Unless you want this site to be all about you, and, you know, fuck the comedy...
